Abstract

The disclosure relates to methods, devices, and systems for preventing a wearable fitness monitor from allowing a transaction, the prevention being based on data obtained using the wearable fitness monitor. Data obtained from motion sensors of the wearable fitness monitor may be used to determine if a transaction should be prevented.

Claims

1. A method, implemented on a wearable fitness monitor comprising one or more motion sensors and one or more processors, the method comprising:

(a) obtaining, by the one or more processors, a motion signature obtained using data from the one or more motion sensors of the wearable fitness monitor configured to be worn by a person, wherein the motion signature characterizes a body movement of the person wearing the wearable fitness monitor;

(b) determining, by the one or more processors, whether the motion signature corresponds to an invalid motion feature, the invalid motion feature characterizing motion likely to be performed by a non-human; and

(c) preventing, based on the determination in (b) and by the one or more processors, the wearable fitness monitor from allowing a transaction.

2. The method of claim 1, wherein the transaction comprises accessing a secure item or providing an award for meeting an activity threshold to a user associated with the wearable fitness monitor.

3. The method of claim 1, further comprising, responsive to determining that the motion signature corresponds to the invalid motion feature, requiring a wearer of the fitness monitor to authenticate himself or herself.

4. The method of claim 3, wherein requiring the wearer to authenticate comprises requiring the wearer of the fitness monitor to input a passcode, a fingerprint, an iris image, an ECG, a facial image, a vocal message, or any combination of the foregoing.

5. The method of claim 1, wherein determining whether the motion signature corresponds to an invalid motion feature in (b) comprises:

obtaining an additional signature using data from one or more additional sensors, and determining that the motion signature, the additional signature, or a combination thereof is inconsistent with at least one human activity.

8. The method of claim 1, wherein the invalid motion feature is a periodic motion having a cycle-to-cycle consistency greater than a threshold.
